ingres_errno

(PECL ingres >= 1.1.0)

ingres_errno — Get the last Ingres error number generated

说明

ingres_errno ([ resource $link ] ) : int

Returns an integer containing the last error number. If no error was reported 0 is returned.

If a link resource is passed to ingres_errno() it returns the last error recorded for the link. If no link is passed, then ingres_errno() returns the last error reported using the default link.

The function, ingres_errno(), should always be called after executing a database query. Calling another function before ingres_errno() is called will reset or change any error code from the last Ingres function call.

参数

link

The connection link identifier

返回值

Returns an integer containing the last error number. If no error was reported, 0 is returned.
